Getting it sharp from a telephoto

Telephoto prime and zoom lenses are among the most useful lenses for a wide variety of genres. They are used for sports, wildlife, travel, and street photography. Many photographers use them for portraits and close-up shots as well.

Technically, telephoto lenses have a focal length or 60mm or more for a standard 35mm or full sensor size camera, though most people think of telephoto lenses having a focal length of 85mm or more. Lenses with a focal length greater than 300mm are considered to be super-telephoto lenses.

Telephoto lenses help us bring distant subjects closer, fill our frame with the subject, show detail difficult to see, capture action, and produce a shallow depth of field.
